Another way to look at it is as an adapter to a "new" WSGI interface specification. The fact that it's backwards compatibile allows it to be used with existing WSGI tools, but future WSGI Lite-compatible software could implement the Lite API directly.
That being said, I've only briefly looked over the WSGI Lite code and neither advocate nor criticize its direction.
I think it just adds the boilerplate back in there for you :)
...so then it's a framework?
Are you serious?
That means that WSGI Lite app can run with WSGI server, not vice versa. At least that's how I understood it.
Correct me if I'm wrong, but doesn't this mean that it's WSGI extra rather than WSGI lite? I mean, you don't generally consider the lite version of something to have the all the features of the full version and then some.
